Who's in Donald Trump's controversial inner circle?
Video report by ITV News Washington Correspondent Robert Moore
It has been a tumultuous year in the Trump administration with an extraordinary turnover of staff at the White House.
At times the White House has seemed like a revolving door with few survivors in Trump’s inner circle - with the latest appointment of outspoken John Bolton as national security adviser raising eyebrows in Washington.
The inner circle includes loyal Trump campaign aides, the president's son-in-law and the advisers who ran his populist, outsider bid for office.
Here's a look at the the people who - for now - have the ear of Donald Trump and how they may shape the policies that are shaking up Washington:
John Bolton, National Security Adviser

A new appointment and one who will share the nationalistic views of the president.
Critics believe that his hawkish approach may lead to military interventions rather than diplomatic solutions.
He's advocated bombing options when discussing North Korea and Iran.
Peter Navarro, White House National Trade Council Director
Mr Navarro is a top economic adviser to the president and director of the White House's Trade and Manufacturing Policy office.
Known as an unapologetic protectionist – he is driving the talk of a trade war. Unsurprisingly, after penning the book, ‘Death by China’.
The former Trump campaign adviser is an economics professor at the University of California, Irvine and is widely believed to be the man behind the tariffs placed on steel and aluminium.
Mike Pompeo, Secretary of State
Replacement for the fired Rex Tillerson and another person that shares the hawkish views of the president.
Speaking about his new Secretary of State, Trump said, "I’ve worked with Mike Pompeo now for quite some time – tremendous energy, tremendous intellect, we’re always on the same wavelength."
Pompeo is a big critic of the Obama administration's nuclear deal with Iran and has opposed closing Guantanamo Bay.
John Kelly, White House Chief of Staff
Kelly is a staunch advocate for hardline policies on immigration.
Previously he's taken full responsibility for Trump's troubled first order for a ban on travellers from some mostly Muslim countries.
But there are suggestions Kelly is having a hard time reigning in the president, particularly his tweets.
His position is also in doubt after rumours that Trump might sack Kelly and not replace him.
Joseph DiGenova, Lawyer to Donald Trump
A new hire at The White House who has been vocal in his support of the president, particularly on the FBI investigation into Russian meddling during the presidential election.
Speaking on Fox News in January, DiGenova said: "There was a brazen plot to illegally exonerate Hillary Clinton and, if she didn’t win the election, to then frame Donald Trump with a falsely created crime."
Jim Mattis, Defence Secretary
Known as the ‘Mad Dog’, Mattis has become – in relation to the rest of his peers – a moderate voice in the ear of Trump, especially on the issues of North Korea and Iran.
However, the Pentagon chief has previously criticised NATO allies for their defence spending and made threats, saying the US would "moderate its commitment" to NATO if more wasn't done.
He did not elaborate on what the US might do if NATO members failed to fall into line.
Mattis wants NATO to set milestone dates for governments to meet the military funding commitment of spending two per cent of GDP on defence.
